apache源于ncsahttpd服务器，经过多次修改，成为世界上最流行的web服务器软件之一。apache取自“a patchy server”的读音，意思是充满补丁的服务器，因为它是自由软件，所以不断有人来为它开发新的功能、新的特性、修改原来的缺陷。apache的特点是简单、速度快、性能稳定，，并可做代理服务器来使用。
linux下apache随机启动
cp /usr/local/apache/bin/apachectl /etc/rc.d/init.d/apached
chmod +x /etc/rc.d/init.d/apached
ln -s /etc/rc.d/init.d/apached /etc/rc3.d/s100apache
ln -s /etc/rc.d/init.d/apached /etc/rc0.d/k100apache
mysql随机启动
默认配置
cp /usr/local/mysql/support-files/mysql.server /etc/rc.d/init.d/mysql
chmod +x /etc/rc.d/init.d/mysql
ln -s /etc/rc.d/init.d/mysql /etc/rc3.d/s100mysql
ln -s /etc/rc.d/init.d/mysql /etc/rc0.d/k100mysql
非默认安装 比如配置在/opt/mysql_server中 创建启动文件/opt/mysql_server/start.sh
#!/bin/sh
rundir=/opt/mysql_server;
echo $rundir;
/usr/local/mysql/bin/mysqld_safe --defaults-file=$rundir/my.cnf --pid-file=$rundir/mysql.pid --datadir=$rundir/data --socket=$rundir/mysql.sock --user=mysql --log-error=$rundir/error.log --log-slow-queries=$rundir/slow_query.log&
创建停止文件/opt/mysql_server/stop.sh
#!/bin/sh
rundir=/opt/mysql_server;
echo $rundir;
/usr/local/mysql/bin/mysqladmin -uroot -pctech --socket=$rundir/mysql.sock shutdown
创建配置文件my.cnf
[mysqld]
port = 8211
